To all whom it may concern:

Be it knownthat I, DANIEL J. Pnmvo, a citizen of'the United States, anda resident of Trinidad, in the county of Las Animas nndState ofColorado, have invented a new and Improved -I lon-Sl-:idding Attachmentfor Automobile-lvheels, of which the following'is a full, clear, andexact 'description. i I

This invention relates to improvements in anti-skidding devices, andparticularly to devices designed 'to be detaehably secured to automobilewheels.

The object in view is to provide an improved structure readily attachedand removed, but whenin-place to positively prevent any appreciableskidding or side-movement of the wheel Another object in view is toprovide an anti-skidding device arranged in a plurality of sections andadapted to "engage the cart as the wheel rotates but formed with meansfor yielding when a hard substance is ena e a 3 still further object ofthe invention is to provide a lurality of yielding segments connectedwiti a wheel and ada ted to engage the ground at one side of t e wheelso as to prevent skidding, these segments bein 50 connected with thewheel as to resist sli ing of the wheel in a forward direction as wellas skidding.

In carrying out the object, of the invention a plurality of segmentalplates are rovided arranged with roughened lower e ges so as to readilyengage the earth. These segments are made of a size to conform to thesize of the wheel on which they are mounted, and are provided withsupporting members held in place by suitable clam s adjustably clampedto the spokes of t e In order that these se mental memhere may engageand press t e earth to a certain extent, but yield when striking a hardsurface, a spring is provided for resiliently pressing the segments intothe earth.

In the accompanying drawing-Figure 1 I is a side view of part of anautomobile wheel with an embodiment of the. invention applied thereto;Fig. 2 is a section through Fig. 1 on line 2- Fig. 3 is a fragmentarysectional view approximately on line 3-8 of Fig. 1; Fig. 4 is adetailedperspective view of the spoke clamp; Fig. 5 is a detailedfragmentary perspective view of one end of the se ment guidingrod.

eferring to the accompanying drawin by numeral 1 indicates an automobilewhee of any kind which is rovided with spokes 2, folly '3 and tire 4.Tiese constructions may be ofany desired kind without departing from thespirit of the invention, as the invention resides not in the wheel butin the attachment connected therewith. A clamping member 5 is arrangedto engage each of the spokes 2, as shown in Fig. 1. Each of the clampingmembers 5 is formed with a portion 6 for clamping the spokes 2, and witha pivotally mounted bolt 7 for pressing the-sides of members 5 againstthe spokes. A winged nut 8 is provided so as to permit easy operation ofbolt 7. IAtthe end of each of the clamping members 5 opposite bolt 7 isan aperture 9' designed to receivea bar 10 which is loosely fittedtherein, as shown in Fig.2. The various clamps 5 may be connectedwithspokes 2 at any desired point. Each of the clamps is provided with aiding bar 10 threaded at the upper en for receiving the limiting nut 11,and formed with a shouldered portion 12 at the bottom against whichpresses spring 13. Spring 18 is designed to press against shoulder 12and against the end of the clamping members 5 associated therewith,whereby the shoulder 12 is normally pressed toward the ground. Bar10-below shoulder 12 is formed with extensions 14, riveted, bolted, orotherwise secured to a segmental contact member 15. The connection 10 ofmember 14 with the segment 15 is preferably pivotal so as to allow aproper yielding action. The segmental members 15 are provided withapertures 17 for permitting the earth and other forei 'n matter pressingbetween members 15 and the tire 4 to pass to the exterior of the segment15.

In operation the various clamping members may be applied and removedquickly without the use of tools as the winged nuts 8 may be easilyoperated by the fingers. When the various segments and associated partshave been connected to the wheel it is ready for operation. Inpassingover the earth spring 13 will cause the lower edge of the varioussegments 15 to enter the earth and thereby effectually prevent any sidemovement or skidding of the wheels. The edge of the segment 15 may besmoothed or roughened lin .any desiredmanner as for instan'eeby beingformed withteeth. When the wheel engages anything hard, as folinstance ahard pavement, the se ment 15 will move upwardly, as shown in Fig. 1,but will of course press tightly against the hard pavement and therebyprevent a skidding action. 'lheaction of the spring 13 may be varied byvarying the position of nut 11. As clearly shown in Fig. 2, the segment15 and associated parts have been raised so as to pass over a hardsurface. When this hard surface is passed the segment 15 will move downautomatically until nut l1'en-- gages the'top of clamp 5. If it shouldbe desired to cause the segment 15, shown in Fig. 2, to further enterthe ground nut 11 will be rotated so as to move farther from clampingmember 5. It will of course be evident that nut ll could-be adjusted forholding the segment 15 from contact with the earth. It will also beevident that the various clamping members .5 may be adjusted. upand-down on their respective spokes so-as to" assist nut 11 in causing aproper engagement of the various segments with theground WhatIclaim'isz-s- 1. Inan anti-skidding device of the character described, a.plurality of segmental plates, a plurality-'ofbars connected'with' eachof said plates, a spring acting on each of said bars for moving saidbars radially, and a clamping bar acting as an abutment for said spring,and as a guiding means for said bars, said clamping member beingadjust-ably connected to a wheel, said clampmg member being formed witha pair of clamping arms engaging said wheel, and a 'pivotally mountedclamping bolt for pinchmg said arms against said wheel.

2. In an anti-skidding dev1ee of the character described, a plurality ofsegmental plates, a bar connected Wlth each of soul plates, a clampingmember for holding said ar ln position on a wheel, said clamping memberbeing provided with an aperture in which said bar is slidinglypositioned, and a pair of resilientjaws, a clamping bolt arranged at theouter end of said jaws for clamping the jaws against the spoke of awheel, and a spring associated with said bar and pressing at one endagainst said segment, and at the other end against said clamping member.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
